[0001] The present invention relates to a multipurpose stand for experiment and, more particularly, to a multipurpose stand for experiment designed to execute experiments safely and accurately by controlling easily the position of experimental instruments and to co-execute various experiments through equipping one tie rod with kinds of experimental instruments.

BACKGROUND ART

[0002] In conventional experimental apparatuses, because experimental instruments for each experiment must be separately prepared and set up, the confusion in executing experiments and the dissipation of materials were caused,

[0003] In addition, the Korean Utility Model Publication No. 97-8251 discloses an experimental stand for fixing heating apparatus wherein the position control of closets was possible during heating a beaker by a alcohol lamp, for the closet can move vertically along tie linkage grooves on the side face of tie rod. However, in execution of various experiments does still exist great discomforts: the restriction which is caused by the dependence of the position control on the linkage grooves; the limitation in kind of experiments, because said experimental stand can fix heating apparatus only; and the problem that the manufacturing cost is high.

DISCLOSURE OF THE INVENTION

[0004] Accordingly, the present invention, taking the above circumstances into consideration, has an object to provide a multipurpose stand for experiment which allow experimenters not only to save time and materials but also to prepare experiments conveniently through the function of co-executing diverse experiments.

[0005] In order to accomplish the above object, the present invention provides a multipurpose stand for experiment, comprising in the main: a tie rod; position-controlling members; and the fixing bars of experimental instruments. And, in detail, the present invention provides a multipurpose stand for experiment possessing the fixing bars of experimental instruments that can easily move and fix the vertical and rotational position of experimental instrument.

BEST MODES FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, the exemplary illustrations of the present invention are described in detail with reference to accompanying drawings.

[0011]FIG. 1 is a perspective view of a multipurpose stand for experiment according to the present invention. FIG. 2 is an exploded perspective view of a position-controlling member and a member to fix the vertical position of said position-controlling member(following, abbreviated to fixing member of vertical position). And FIG. 3 is a perspective view showing the using state of multipurpose stand for experiment according to the present invention, with various experimental instruments assembled.

[0012] First of all, as illustrated in FIG. 1, the present invention provides a multipurpose stand for experiment, comprising: a pedestal (25); a tie rod (27) vertically erected on said pedestal (25); several position-controlling members (15), inserted into said tie rod (27), which can easily move vertically and rotationally; several fixing members of vertical position (17), closely adhered to the bottom face of said position-controlling members (15), which fix the position of said position-controlling members by clamp screws (20); fixing bars of experimental instruments (37, 38), adhered to the grooves (15 c) on the upper side face of said position-controlling member (15), one end of which is adhered to said position-controlling members and the other of which is equipped with kinds of experimental instruments; and thermometer-putting bars (24) adhered to the spar-parts (37 b, 38 b) of said experimental instrument fixing bars (37, 38).

[0013] As described in FIG. 2, each of said position-controlling members (15) comprises: a through bore (15 a), along within which said position-controlling member (15) is inserted into said tie rod (27); several grooves (15 c), formed on the upper side face of said position-controlling member (15), with which fixing bars of experimental instruments (37, 38) are assembled; trapped holes (15 b) orthogonal to said grooves (15 c) for putting clamp screws (20) into, on the top face of said position-controlling member (15); and one trapped hole (15 d), in the lower side face of said position-controlling member (15), for inserting a clamp screw into. And, each of said fixing member of vertical position (17), the same as said position-controlling member (15), is composed of a through bore (17 b) for inserting said tie rod (27) into and a trapped hole (17 a) for putting a clamp screw into.

[0014] In virtue of cylindrical form and metal plated inner surface of said through bore (15 a), said position-controlling member (15) can regulate the rotational position easily. In addition, the rotational position is fixed by inserting a clamp screw (20) into said trapped hole (15 d) formed on the lower side face. The control and fixation of the vertical position is accomplished by adhering the fixing member of vertical position (17) to the bottom of said position-controlling member and inserting a clamp screw (20) into said trapped hole (17 a).

[0015] As shown in FIG. 1 the fix bars of experimental instruments (37, 38) are classified into two groups, one of which is in the shape of a ring (37) to install a beaker, a funnel, a separating funnel etc., and the other of which in the shape of a clamp (38) to grip experimental instruments having small inlet diameter like a test tube, a flask and so forth.

[0016] Said ring-shaped fixing bar of experimental instruments (37) is composed of a spar-part (37 b) and a ring-part (37 a), and the diameter of the ring-part (37 a) is manufactured diversely according to the size of the experimental instruments like a beaker, a funnel, a separating funnel and so forth.

[0017] Said clamp-shaped fixing bar of experimental instruments (38) is composed of a spar part (38 a), and a clamp-part (38 b).

[0018] The control and fixation of said fixing bars of experimental instruments (37, 38) is achieved by adhering said fixing bars of experimental instruments (37, 38) to the grooves (15 c) formed on the upper side face of said position-controlling member (15) and, thereafter, by regulating the clamp screws (20) putted into the trapped hole (15 b) formed on the top face of said position-controlling member (15). Especially, the thermometer-putting bar (24), adhered to the spar-part (37 b, 38 b) of said fixing bar of experimental instrument (37, 38), comprises; a control unit (24 a); a clamp screw (24 c) to fix said control unit (24 a); and a thermometer-putting portion (24 b), in the shape of “inverted L”, assembled with said control unit (24 a). Thereupon, the thermometer putting bar (24) can easily shift laterally along the spar-part (37 b, 38 b) of said fixing bar of experimental instrument and move rotationally in perpendicular direction to the horizontal axis, and, moreover, the inverted L-shaped thermometer-putting portion (24 b) itself can rotate easily.

[0019] Accordingly, as illustrated in FIG. 3, the ability of controlling and fixing the vertical and the rotational position of experimental instruments enables experimenters to co-execute various experiments through equipping several fixing bars of experimental instruments with beakers, round bottom flasks, thermometers, alcohol lamps, etc. at the same time.

[0020] As shown in FIG. 1 the fixing bars of experimental instruments (37, 38) are classified into two groups, one of which is in the shape of a ring (37) to install a beaker, a funnel, a separating funnel etc., and the other of which in the shape of a clamp (38) to grip experimental instruments having small inlet diameter like a test tube, a flask and so forth.

[0021] Said ring-shaped fixing bar of experimental instruments (37) is composed of a spar-part (37 b) and a ring-part (37 a), and the diameter of the ring-part (37 a) is manufactured diversely according to the size of the experimental instruments like a beaker, a funnel, a separating funnel and so forth.

[0022] Said clamp-shaped fixing bar of experimental instruments (38) is composed of a spar-part (38 a), and a clamp-part (38 b).

[0023] The control and fixation of said fixing bars of experimental instruments (37, 38) is achieved by adhering said icing bars of experimental instruments (37, 38) to the grooves (15 c) formed on the upper side face of said position-controlling member (15) and, thereafter, by regulating the clamp screws (20) putted into the trapped hole (15 b) formed on the top face of said position-controlling member (15). Especially, the thermometer-putting bar (24), adhered to the spar-part (37 b, 38 b) of said fixing bar of experimental instrument (37, 38), comprises: a control unit (24 a); a clamp screw (24 c) to fix said control unit (24 a); and a thermometer-putting portion (24 b), in the shape of “inverted L”, assembled with said control unit (24 a). Thereupon, the thermometer putting bar (24) can easily shift laterally along the spar-part (37 b, 38 b) of said fixing bar of experimental instrument, and move rotationally in perpendicular direction to the horizontal axis, and, moreover, the inverted L-shaped thermometer-putting portion (24 b) itself can rotate easily.

[0024] Accordingly, as illustrated in FIG. 3, the ability of controlling and fixing the vertical and the rotational position of experimental instruments enables experimenters to co-execute various experiments through equipping several fixing bars of experimental instruments with beakers, round bottom flasks, thermometers, alcohol lamps, etc. at the same time.
